Re: External monitor T500

lot of the dell ultrasharp LCD have displayport connectivity. If you use a simple passive displayport to dvi adapter, you can still get WUXGA resolution (usually 24 inch LCD all have that), if you need the WQXGA resolution for DVI equipped monitors, get a Dell Active Displayport to Dual Link DVI adapter.

Re: External monitor T500

I am having similar problem in determining compatibility. I purchased a Dell SB2010 20" external monitor for a ThinkPad T500. The prior 17" monitor had no display issues; however, the Dell becomes intermittently fuzzy and "squiggly" (for lack of a better term), and then clears. This pattern is fairly consistent.

The ThinkPad is less than a year old and the drivers are up to date. I adjusted the refresh rate from 60 to 75, and that appeared to initially help but then it went back to the fuzzy/clear pattern. I also adjusted the resolution (note, the Dell recommendation is 1600x900, however, that option is not available on the Lenovo).

I have checked the connections and the cables, and can identify nothing that seems to be the culprit. I plugged the monitor into an older desktop and it seems to be fine, which would point to the Lenovo settings.

Re: External monitor T500

Thank you for your response; however, I don't know what a passive displayport to dvi adapter is - is it a small piece of hardware that connects the monitor cable to the laptop or docking station? Also, it's not a 24-inch LCD, it's 20-inch - does that make a difference? What's the difference between WUXGA and WQXGA and which one is the best? Finally, do I need to worry about "dual link"?

Apologize, we are a small law firm and don't typically work with graphics terms, so if you can "dumb it down" for me, I would appreciate your help! Thanks again!

Active Displayport to DVI adapter has dual link DVI out and requires a usb port (basically a dual link dvi out is used in anything larger than a 24 inch WUXGA (resolution of 1920 x 1200) screen, it supports WQXGA (resolution = 2560 x 1600@60hz refresh rate) which are found in many top end 30 inch desktop LCDs.

--------------------

also are you using the vga cable (blue cable usually) or dvi cable (usually white) on the monitor? To get the 1600 x 900 you must update the bios of your T500. So what is your full model number (found under the laptop on a stickers) it is in the form of xxxx-xxx?
